Write the absolute value inequality in the form x−b ≤c or x−b ≥c that has the solution set −1≤x≤3.

Answers

Answer 1
Answer:

The solution set of | x - 1 | ≤ 2 is -1 ≤ x ≤ 3, as required.

What is inequality?

A connection between two expressions or values that is not equal to each other is referred to as "inequality" in mathematics. The inequality can be resolved by adding the same amount to each side, subtracting the same amount from each side, multiplying or dividing each side by the same positive integer, and more. If you multiply or divide either side by a negative value, you must flip the inequality sign.

To write the absolute value inequality in the form x−b ≤c or x−b ≥c, we need to identify the midpoint between the lower and upper bounds of the solution set.

The midpoint is (3 - 1)/2 = 1.

Then, we can write the absolute value inequality as:

| x - 1 | ≤ 2

To verify that this inequality has the solution set -1 ≤ x ≤ 3, we can solve it as follows:

If x - 1 ≥ 0, then | x - 1 | = x - 1, and we have:

x - 1 ≤ 2

x ≤ 3

If x - 1 < 0, then | x - 1 | = - (x - 1), and we have:

(x - 1) ≤ 2

x - 1 ≥ -2

x ≥ -1

Therefore, | x - 1 | ≤ 2.

Convert 11.42424242 … to a rational expression in the form of a over b, where b ≠ 0.

Answers

Answer:

x  = (1131)/(99).

Step-by-step explanation:

Given  : 11.42424242 …

To find : Convert it to a rational expression in the form of a over b, where b ≠ 0.

Solution: We have given 11.42424242 …

We can see here two number 42 are repeating.

Let x = 11.42424242 …

On multiplying both sides by 100

100x = 100 * 11.42424242 …

100x = 1142.424242.....

100x = 11.4242.....+1131.00000.....

100x = x + 1131.0000....

On subtracting both sides by x

100x -x = 1131

99x = 1131.

On dividing both side by99.

x  = (1131)/(99).

Therefore, x  = (1131)/(99).

11.42... = 11 42/99 = 1131/99 reduces to 377/33

There are 5 sides in a Pentagon so just multiply a side by 5.

How do you now 11/33 is a simplest form

Answers

it is not the simplest form. the simplest form would be 1/3. this is because with such a fraction as 11/33, you have a common factor with them, which is 11. reduce the fraction until there are no common multiples for the numerator and demonimator. 

33=11+11+11 so 11/33=11/(11+11+11) represent a third part of an integer
so 11/33=11/(3x11)=(11/11)x(1/3)=1/3=0,(3) can be simplified by 11, so its not  simple form as 1/3 is

What is 4 times 4 over 5

ok so if u change 4 into an improper fraction,you can work out the problem.so 4 times 4/5=4/1 times 4/5=16/5=3 1/5

In 2007, the US population was 302 million people. In 2012, and 314 million. What was the rate of the population change per year?

Answers

The correct answer is:

2.4 million.

Explanation:

To find the rate of change, first we find the amount that the population grew in the time period:

314-302 = 12

Now we calculate the number of years:

2012-2007 = 5

Divide the amount of change by the number of years:

12/5 = 2.4

The population grew by 2.4 million people per year.

314 - 302 =12 / 5 = 2.4,

the population grows 2.4 percent of people a year.
